BENCH -PLANE.

SPECIFICATION forming part of Letters Patent No. 291,815, dated January8, 1884.

Application filed November 23, 1883. (N0 model.)

To all whom, it may concern:

Be it known that I, J USTUS A. TRAUT, a citizen of the United States,residing at New Britain, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements in BenchPlanes, of which the following is a specification.

My invention relates to improvements in bench-planes; and the object ofmy improvement is to make a cheap and convenient form of convertiblebull-nozed and common hand plane. Such convertible planes haveheretofore been made by a change in the position of the cutter. I attainthis object by the construction illustrated in the accompanyingdrawings, in which- Figure 1 is a side elevation of my converti- Fig. 2is a partial plan View and section thereof on line :0 0c ofv Fig. 1.Fig. 3 is a side elevation of the same arranged for use as a bull-nozedplane.

The term bull-nozed is used to denote a plane in which the cutting-bit Aextends practically to the forward end of the stock, to enable the planeto be used in planing up against a shoulder and in cramped places. Suchplanes are well known in the art.

For the ordinary uses of a hand-plane, the forward end of thecutting-bit should be a little forward of the middle of the stock.

As shown in Figs. 1 and 2, my plane is so arranged for use as anordinary block-plane. The general form of the stock B and theconstruction of the adjusting and holding mechanism may be of anyordinary character. I form the forward end of the stock proper, B, witha vertical face or seat, 0, upon which I secure the attachable anddetachable stock-extension C by means of a screw, 0. It is also furthersecured by means of dowels b 11, se- 40 erly secured to the stock B, thebottom face of 5 the whole stock is planed or smoothed off, as shown inFig. 1. The extension C then constitutes a part of the stock, and theplane is substantially the same for all the uses of the ordinaryhand-plane as if the extension C were made integral with the stock B.When it is desired to convert the instrument into a bullnozed plane, itis only necessary to remove the fastening-screwa and the extension C,when a well-balanced bull-nozed plane remains, as shown in Fig. 3.

By my improvement I produce a convertible bull-nozed and hand plane at asmall exp'ense, and in which both forms of plane are left in theirordinary characteristic and wellbalanced form, and in which the cutteris not necessarily removed in changing from one form of plane to theother, and in which there is plenty of room to arrange the ordinaryadjusting mechanism underneath and in the rear of the cutter.

I claim as my invention- The herein-described convertible plane,consisting of the stock B, adapted to receive and hold the cutting-bit,and provided with the attachable and detachable stock-extension O,substantially as described, and for the purpose specified.
